Title:
PROCESS FOR PRODUCING CYCLOOLEFIN POLYMER, CYCLOOLEFIN COPOLYMER, AND COMPOSITION AND MOLDING PREPARED THEREFROM
Document Type and Number:
WIPO Patent Application WO/1992/006123
Kind Code:
A1
Abstract:
An efficient process for producing cycloolefin polymer and cycloolefin/$g(a)-olefin copolymer without causing any ring opening of the cycloolefin; novel cycloolefin/$g(a)-olefin copolymer produced thereby; and composition and molding prepared from said copolymer. The production process comprises conducting the homopolymerization of cycloolefin or the copolymerization thereof with $g(a)-olefin in the presence of a catalyst based on the following components (A) and (B) or (A), (B) and (C); A: transition metal compound, B: compound which forms ionic complex by the reaction with transition metal compound, and C: organoaluminum compound.
